ASTM D1079-10

This document is not anASTM standard and is intended only to provide the user of anASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

2. Terminology
2.1 Definitions:
accelerated weathering, v—the exposure of a specimen to a specified test environment for a specified time with the intent of
producing, in a shorter time period, effects similar to actual weathering.
aggregate—(1) crushed stone, crushed slag, or water-worn gravel used for surfacing a built-up roof;
(2) any granular mineral material.
alligatoring—thecrackingofthesurfacingbitumenonabuilt-uproof,producingapatternofcrackssimilartoanalligator’shide;
the cracks may not extend through the surfacing bitumen.
anionic emulsion—an emulsion in which the emulsifying system establishes a predominance of negative charges on the
discontinuous phase.
application rate—the quantity (mass, volume or thickness) of material applied per unit area.
artificial weathering, v—exposure to conditions, which may be cyclic, involving temperature, relative humidity, radiant energy,
and/or any other conditions or pollutants found in the atmosphere in various geographical areas, which may accelerate changes
in properties of materials over those of natural weather conditions.
asbestos—a group of natural fibrous impure silicate materials.
asphalt—a dark brown to black cementitious material in which the predominating constituents are bitumens that occur in nature
or are obtained in petroleum processing.
asphalt, air blown—an asphalt produced by blowing air through molten asphalt at an elevated temperature to raise its softening
point and modify other properties.
asphaltene—a high molecular weight hydrocarbon fraction precipitated from asphalt by a designated paraffinic naphtha solvent
at a specified temperature and solvent-asphalt ratio.
DISCUSSION—The asphaltene fraction should be identified by the temperature and solvent-asphalt ratio used.
asphalt felt—an asphalt-saturated felt.
